The operation of the above structure will be explained based on the schematic plan view of FIG. 8 and the driving cycle diagram of FIG. 9. First, in Fig. 4 and Fig. 8, the section from hem to ri is the driving section α, and the driving section α is the 9th section.
The cam groove 32 is formed so as to obtain the driving stroke indicated by β in the figure. Next, when the drive device 49 is activated, the rotary table 19 is rotated in the direction of arrow A through the gears 48, 47, and 50, the supply star wheel 9 is rotated in the direction of arrow C, and the discharge star wheel 10 is rotated in the direction of arrow D. direction, turntable 5
1 is rotated in the direction of arrow B, respectively. Next, the container 1 transported by the screw feeder 8 in the direction of arrow E is sent into each recess 21 of the rotary table 19 by the supply star wheel 9 and placed on the turntable 51. Next, as the turntable 51 rotates, the container 1 thereon is rotated in the direction of arrow B, and the protrusion 1A is moved against the stopper block 56.
When this happens, both handle drive holes 2 and 3 coincide with the notch 22. Next, when both grippers 41 and 42 of each set that rotate together with the rotary table 19 approach the magazine 39, the cam floor 45 of the front gripper 42 rides on the protrusion 61 of the lower cam ring 46B, and the tip of the front gripper 42 is removed from the magazine 39. Rotate it away. Therefore, the front gripper 42
passes through without engaging the handle 4 in the front row of the magazine 39, and the tip of the rear gripper 41 engages the handle 4 in the front row of the magazine 39, and the handle 4 in the front row is moved to the arcuate guide section 40. Push it inward. The handle 4 pushed out into the arcuate guide part 40 has a projection 61
Since the front gripper 42 and the rear gripper 41 that have entered the arcuate guide section 40 are held together by the spring 43, the gripper 41 is integrated with the rotary table 19 and moves in the direction of arrow A. be rotated. Next, when the handle 4 comes to just before the RO position, the tip of the front gripper 42 is separated from the handle 4 by the protrusion 62 of the lower cam ring 46B.
Next, the tip of the rear gripper 41 also separates from the handle 4 by the protrusion 63 of the upper cam ring 46A, and the handle 4 falls due to its own weight and enters the handle support guide 28 waiting below. The handle 4 that has entered the guide 28 is temporarily fixed by the leaf spring 58 and will not fall. Next, when the handle 4 in the handle support guide 28 is brought to the "H" position, the cam groove 32 begins to lower, and the elevating body 29 shown in solid line in FIG.

6, the guide 28 as shown by the imaginary line in FIG.
Go inside and start descending. This striker 33
As the handle 4 is lowered, the handle 4 temporarily fixed in the guide 28 is pushed down, and the tip 4A of the handle 4 passes through the upper handle drive hole 2 and then into the lower handle drive hole 3.
It penetrates through the inside (as shown by the solid line in Figures 1 and 2).
During this driving, since the handle 4 is supported by the leaf spring 57 between the handle driving holes 2 and 3, the handle 4 will not bend at the thin parts 4D and 4E. Next, the driving is completed at the second position, and the protrusion 1 with the handle 4 is conveyed in the direction of arrow F by the conveyor 11 via the discharge side star wheel 10.

As described above, according to the present invention, the handle can be attached to each container by automatically driving the tip of the handle into the handle driving hole of each container. Furthermore, since the handle is temporarily fixed within the handle support guide by the handle temporary fixing means, the handle will not fall out of the handle support guide or be displaced before it is driven in.
